E-Commerce covers a broad range of inter-connected processes which eventually leads to a transaction between two or more parties. Recent enhancements in technology, specifically social interactions on the Web, have increased the complexity in analyzing these processes and describing E-Commerce as a whole. And, to be honest, there is a lot of confusion within the terminology of “E-Commerce” itself. The exact definition of E-Commerce varies depending on your source, and you might hear words like e-business, e-retailing, and online shopping all used interchangeably. Mind you, they all have different meanings.
